Abstract:
Horticultural commodities still have important roles in supporting the economy of Indonesia. One of the many horticultural commodities grown farmers in Indonesia is caisim its production reached 583.770 tons in the year 2010 and decreased to 580.969 tons in the year 2011 (BPS, 2012). Therefore, the need for efforts to increase production of caisim either an intensification, extensification or diversification. Utilization of marginal lands for cultivation of the plant caisim is one of the ways to improve production. This research aims to know the interactions from the rest of the amendments and fertilizers NPK plant growth and production of caisim (Brassica Chinensis) in the peat. This research was carried out in an experimental Garden UPT Faculty of Agriculture University of Riau JL. HR. Soebrantas KM 12.5 Panam Pekanbaru. The implementation took place in October and November 2012. This research is a 2 x 4 factorial experiment contains a complete Random Design was compiled (RAL) consists of 8 combination treatment that consists of 3 repeats so there are 24 units of the experiment. Each unit has 2 plants so obtained total 48 plants. Next to 2 plants were sampled in each unit. The Data obtained were analyzed statistically with the fingerprint. If the count is greater than F F table then conducted further trials of different real honest (BNJ) on a real level of 5%. The combination of NPK fertilizers and dolomite of the influential widespread leaf and plant root volume caisim. But the granting of NPK fertilizers and dolomite effect is not real high on plants and plant fresh weight caisim. awarding amendments 40 gr/polybag with 100% NPK dosage recommendations (D1N2) is a combination of the best treatment.
